What is the ParlayMarket App?

The ParlayMarket App is a prediction market research and paper-ticket workspace. Explore markets and build tickets without a wallet, then optionally connect, sign your intent, and save a ticket for venue review.

How do parlay tickets work?

A paper ticket groups selected market outcomes and an illustrative stake. Combined probabilities assume independent outcomes; related outcomes can change the result. Displayed returns are estimates, with no fees or margin, and are not a venue quote or a purchased position.

Does signing a ticket place a bet?

No. Signing records your ticket intent, and saving preserves that record. Neither action places a bet or submits a venue order. Demo signatures remain local.

What happens when I continue at a venue?

The handoff opens a named venue in a new tab so you can review market availability, current prices, rules, and eligibility there. The venue handles sign-in, consent, order submission, and settlement. Opening a link does not complete a trade.

What does handoff history verify?

History distinguishes prepared handoffs, observed link openings, and actions you report from externally verified results. A user-reported action alone is not verification.

Estimate = stake × combined odds. Assumes independent outcomes; correlated picks can overstate the payout. Prices may change.

Your ticket updates as you go. Changing a pick or stake clears the previous signature.

Adapter notes

The app is designed so that a backend / adapter can:

Serve normalized markets to the app (instead of static JSON).
Receive this ticket object on a /api/quote or /api/float endpoint.
Respond with a live quote ID and expiry for execution.
